The project is a part of the underground metro and tunnel in Sweden.Â
Challenges
The mega column has footing, columns, and a beam. Further, beams had irregular hexagon shape with reduced size on both sides of the beam span. In addition, beam has slopes on top. Because of the underground location of the structure, it has heavy reinforcement and a complex rebar arrangement. Â
All longitudinal bars are inclined reducing the cross-section of the beam. Along with shorter directions, each bar has a different length due to reducing beam size. Moreover, heavy reinforcement had clash issues in 2D detailing.
Benefits of using TeklaÂ
- This project had already been completed in 2D drawings, but the rebar drawings were not sufficient to help understand the placement of rebar and their congestion. The customer had mandated Tekla Structures for rebar modelling.
- Tekla's rebar modelling helped to resolve clash issues and fix the upcoming field issues in the primary stage of modelling.Â
- This project has helped to avoid the congestion of rebar in the field and saved wastage of steel.
- Tekla Structures unique capabilities helped the project team to execute rebar modelling for such irregular hexagon profile of concrete with slopes on all edges of the beam.
- Irregular bend shape with accurate BBS was generated on Tekla to match with the geometry of concrete.
